“The scientific study of suffering inevitably raises questions of causation, and with these, issues of blame and responsibility. Historically, doctors have highlighted predisposing vulnerability factors for developing PTSD, at the expense of recognizing the reality of their patients' experiences… This search for predisposing factors probably had its origins in the need to deny that all people can be stressed beyond endurance, rather than in solid scientific data; until recently such data were simply not available… When the issue of causation becomes a legitimate area of investigation, one is inevitably confronted with issues of man's inhumanity to man, with carelessness and callousness, with abrogation of responsibility, with manipulation and with failures to protect.”
